4 Trends and Challenges in Engineering Design for Medical Inventions -written by Poonam Chanchlani (BCA, Data Science)

In an insightful exploration,  Bhandari and colleagues (2023) delve into the dynamic realm of 3D-printed heart valves and other cardiac implants . This comprehensive review captures the zeitgeist of this transformative technology, unveiling a panorama of trends and hurdles. With a thrust towards personalized healthcare and regenerative medicine, 3D printing is steering cardiology towards unprecedented frontiers.

 

The article navigates through an array of organic and synthetic polymers employed in crafting 3D-printed heart valves. These building blocks, each bearing unique attributes, shape the landscape of cardiac innovation. Collagen, fibrin, and chitosan, naturals polymers, stand as catalysts for tissue rejuvenation. Meanwhile, the synthetic realm boasts polyglycolic acid (PGA), poly(l-lactic acid) (PLLA), poly(lactic-co-glycolic acid) (PLGA), poly(ε-caprolactone) (PCL), and polyurethane (PU) - materials that seamlessly marry biodegradability, biocompatibility, and mechanical prowess.

 

Stem cells emerge as protagonists in the narrative of cardiac tissue engineering. Their chameleon-like adaptability and regenerative prowess offer promises of mitigating immunological rejections and thrombogenic dilemmas. A symphony of computer-aided design (CAD) and manufacturing (CAM), choreographed with medical imaging, births bespoke heart valve designs that stand as testaments to patient specificity.

 

The discussion radiates beyond heart valves, extending its embrace to pacemakers (PMs) and ventricular assist devices (VADs). These technologies unfurl against the backdrop of congestive heart failure and the quest for viable heart transplants. 3D printing's indelible mark on this domain is reflected in PMs designed in alignment with patients' uniqueness and enriched diagnostic capabilities.

 

Bhandari and colleagues (2023) crescendo their exposition by underlining the transformative capacity of 3D-printed cardiac implants. Customization, enhanced biocompatibility, and optimized functionality stand as the cornerstones of this revolution. The article resonates with a clarion call to push beyond boundaries, revolutionizing cardiac healthcare and illuminating the path to regenerative triumph.
